Description
The Cisco® SFP25G-LR-S-I-DW3190 Compatible 25GBase-DWDM SFP28 Transceiver delivers reliable 25Gbps data transmission up to 10km over single-mode fiber (SMF) using a 1531.90nm wavelength via an LC duplex connector. Designed for industrial temperature environments (-40°C to 85°C), this module ensures stable performance in demanding applications such as access, metro, and enterprise networks.
Hot-pluggable and fully compliant with SFF-8432 and SFF-8472 standards, the transceiver features Digital Optical Monitoring (DOM) for real-time performance management, and is built with excellent ESD protection and low EMI metal housing. Each unit is uniquely serialized, application-tested, and guaranteed 100% compatibility with Cisco® equivalents. This TAA-compliant module comes backed by AddOn’s limited lifetime warranty for long-term peace of mind.
